"J.J. will continue to develop projects for us including a new Mission: Impossible, and he is committed to produce another Star Trek."
It also remains possible that J.J. Abrams will be back to direct Star Trek 3. Since there is a four-year gap between 2009's Star Trek and Star Trek Into Darkness, opening on May 17, it may be possible for J.J. Abrams to return and direct Star Trek 3 for a 2017 release. However, if Star Trek Into Darkness is an even bigger hit than Star Trek, Paramount may not want to wait that long.
